I am not sure about public interest anymore, but I would suspect we would have to correct a lot of the ideas we had about the “old west” and that may be why there are less of them. If you think about it, most of the old westerns depicted the American Indian as a rather mindless, and ruthless fool. Women were usually helpless souls, and the men either the total bad guy or hero.
A true to life western might actually be a good thing, but I don’t think most people would like it. Life was mean, many times women spent years alone working the land, while men sought work and were elsewhere, there were attacks by the Indians, but we usually attacked first and have to remember we took over their land and pushed them off it and out of their way of life, death rates where high, then we had slavery to deal with, the Chinese built our railways for us . . . etc. Sure there was good being done in all this, but there was also a high level of lawlessness and things were not that “romantic.”
I would rather see a western that was more truthful and honest, but I am sure many would find such a program less interesting than those with the old saloon, cowboys and Indians fighting, and successful ranches and farms. If you were not tough in those days you simply died.
